Application May 26, 1951,Serial No. 228,411

This invention relates to an improved double pane window sash assembly. One object of the invention is to provide a double. pane window sash assembly so constructed'that'the separate panes are independently'readily and easily replaceable.

Another object is to provide a'double pane window sash assembly so constructed'that the separate panes are independently mounted in individual sash and two such separate sash are secured togetherto form thedouble'pane assembly and the individual sash are readily and easily replaceable.

A further object is to provide a double pane window sash assembly which is of simple inexpensive construction and wherein two individual sash are secured together to form the double pane sash assembly and th construction is such that ventilating air passageways areprovided through the sash into'the space between the two panes.

More particularly, an object is to provide a double pane window sash assembly which consists of two individual wood'sash, the opposite side rails of which are provided with outwardly projecting ledges extending lengthwise of the rails and flush with the juxtaposed faces thereof, said sash being so secured together that such ledges are arranged in abutting relationship and a metal channel is provided extending along over and embracing said ledges. The'top and bottom railsamay also be provided with ledges and metal channels may be fitted thereover. Preferably, the channels are so secured upon the ledges that there is a space between the bottom of each channel and the ledges received therein. The upper pane sash is also preferably provided with an air passageway extending from the space between the two panes through the sash into the space between the bottom of the channel and the ledges.

Other objects, advantages and meritorious features will more fully appear from the following specification, claim and accompanying drawing, wherein:

Fig. 2 is a side elevation of a sash as shown in Fig. 1;

Fig. 3 is a cross sectional view taken on the line 3-3 of Fig. 1;

Fig. 4 is a cross sectional view of a modification of the structure shown in Fig. 3;

Fig. 5 is a side elevation of a modification of my invention;

Fig. 6 is a fragmentary corner perspective of the structure showninFigj;

Fig. I is a fragmentary .corner perspective of a sash embodying th invention s'lidably engaged with ajamb member formed to receive the-same;

Fig. 8 is a fragmentary sectional view taken on the'line 8-.8 of Fig.5;

Fig. 9 is a fragmentary sectional view-taken on the line 9--9 of Figi'l; and

Fig. 10 is a fragmentary sectional view taken on the line Ill-l0 of Fig.7.

The construction shown in Figs. v -1 through '4 represents a simple embodiment of the inven-- tion which comprises apairof complementary individual wood sash Ill-"20 eachprovided with a window pane 22 mounted'therein in the usual manner. Each individual sash comprises a pair of opposed side'rails, a toprail and a bottom rail, as is conventional. Each sashjis shown in Fig.3 as having the opposite'rails rabbeted exhibiting an outwardly projectingledgeil which extends lengthwise of the railrflush with 'theiinner face of the sash and a shoulder '26 which extends lengthwise of the rail along the outer fac of the sash. The two individual'sash'are arranged in side-'by-sid relationship with the ledges 24 juxtaposed and as shown in Fig. '3 the two sash may be secured togetherby screws". One screw is shown in Fig. '3 butitheymayEbe-provided-in such "numberas is desired. In Fig. 2, fourisuch screws'are shown.

In order toiprovide atight fitting junctionbetween the 'juxtapose'dslnfaces of :the sash, sultable caulking compound 30, such as a suitable putty, may be'spread over'the faces "of the'sash to be juxtaposed and when the two sash are secured together this caulking compound forms a tight seal.

A metal channel member 32 is provided and extends along over and embraces the juxtaposed ledges 24 and an adhesive caulking material 34 is spread over the inner surfaces of this channel member so as to form a tight seal between the walls of the channel and the surfaces of the ledges and securing the channel to the ledges all as shown in Fig. 3. The channel 32 may extend along over each rail of the sash as shown in Fig. 1.

In Fig. 4, a modification is shown in that the sash elements 20 are arranged side by side and secured together a heretofore described with caulking compound 30 therebetween. The rails are not rabbeted, however, and a metal channel 36 is received over the corresponding rails of the two individual sash and secured thereto by an adhesive caulking compound 34 as heretofore described.

In Figs. and 6, a modification is shown which is the preferred form of construction. This modification illustrates a double pane sash assembly of the same general character heretofore described. There are two individual sash each provided with a pane 22. These sash are secured together in side-by-side relationship by screws 28 or the like. Each sash has certain rails rabbeted as heretofore described providing juxtaposed ledges 24 and shoulders as heretofore set forth. A metal channel 32 extends along over and is secured to and embraces the juxtaposed ledges 24. This securement may be by means of suitable adhesive or in any other suitable manner. A feature of the construction shown in these figures is however that the ledges 24 do not seat upon the bottom of the channel but a space is provided between the bottom of the channel and the ledges which space is shown in Figs. 6 and 8 and indicated as 38.

A ventilating air passageway 40 extends through the sash from the space between the two panes 22 to the space 38 between the ledges and the bottom of the channel. This space 38 between the bottom of the channel and the ledges is open at the ends of the channel as shown in Fig. 6, at 38. These passageways Mirnay extend between the two individual sash and have a downward inclination as illustrated in Fig. 5 for better drainage.

In these figures, the side rails of the sash are the only rails shown as provided with passageways 40 and it is therefore these side rails which alone exhibit the idea of the space 38 between the bottom of the channel and the ledges. The top and bottom rails of the sash may have a channel seated snugly against the ledges as shown particularly in Fig. 7.

In Figs. 7, 9 and 10, the double sash assembly is shown as slidably engaged with a window jamb =portion. There is a jamb member 42 provided with an inner stop 44 and an outer stop 46. Disposed between the two stops are cooperating metal run-way strips 48. Each run-way strip exhibits a sash guide channel. The two strips have overlapping portions 50 as shown. The sash itself is formed with the ledges 24 all as described heretofore and the individual sash are suitably secured, likewise as heretofore described. These ledges 24 are slidably disposed within the guide channels of the guide rails 48 as shown in Figs. I and 9 for slidable movement of the sash therein. It will be seen that the ledges do not seat against the bottom of the window guide channels but a space is provided between the ledges and the bottom of the guide rails into which space the ventilating passageways 40 extend through the sash. In these Figures 7, 9 and 10, the metal channels form a stationary part of the window jamb structure and then being secured to the sash as described in connection with the structure of Figs. 5, 6 and 8.

What I claim is:

A double pane, window sash assembly comprising, in combination, a pair of identical complementary window sash each provided with a window pane, the outer faces of the side rails of said sash cut away adjacent the edges thereof providing a shoulder and a ledge in each rail, transverse grooves formed in the inner faces of said rails with each groove extending completely thereacross and opening at each end adjacent the window pane and the edge of said ledge, said sash adapted to be juxtaposed with said grooves in register and with the edges of the said rails flush with one another, a U-shaped channel member adapted to be received over said ledges when the sash are juxtaposed with the legs of the channel grippingly engaging the sides of said ledges adjacent said shoulders and bearing against said shoulders and with the bottom of the channel spaced outwardly from the said flush edges of the ledges providing an air space coextensive therewith, said transverse grooves communicating with the spaces between said window panes and between said edges and the bottom of said channels when the sash are juxtaposed as before described.
